Lab Mission
Welcome to the Doloff Lab for Immunoengineering and Regenerative Medicine. Our mission is to explore the intersection between therapeutics, whether biologic or synthetic in origin, and living systems to better understand what happens when deliverables are introduced into the body and how the host immune system behaves as well as perceives them.
Principal Investigator
Joshua C. Doloff is a newly appointed Assistant Professor in Biomedical Engineering and Materials Science and Engineering at Johns Hopkins University’s School of Medicine. He was previously a Juvenile Diabetes Research Foundation (JDRF) Senior Postdoctoral Fellow in the labs of Robert Langer and Daniel G. Anderson in Chemical Engineering and the David H.

Latest News
New humanized mouse model for screening medical implant fibrosis and failure
A team of researchers led by Joshua Doloff, an assistant professor of biomedical engineering, has discovered an advanced “humanized” mouse model to better predict how the human immune system will react to medical implants. Their results appear in Science Advances. …. FULL STORY HERE
Smoothing the Way to Better Breast Implants
Silicone breast implants with a smoother surface design have less risk of producing inflammation and other immune system reactions than those with more roughly textured coatings, according to new research by Joshua Doloff, assistant professor of biomedical engineering, who collaborated with researchers at Johns Hopkins Medicine, MIT, and Rice University on a series of experiments published last June in Nature Biomedical Engineering. ….

Drug Crystals to prevent medical device fibrosis
Implanted medical devices can save lives, but can also put patients at the risk of fibrosis, a condition in which the immune system attacks the device and produces scar tissue around it, interfering with the device’s functionality. Working with researchers at Massachusetts Institute of Technology, Joshua Doloff, an assistant professor of biomedical engineering at Johns Hopkins University and former MIT postdoc, has devised a new way to prevent fibrosis: loading implantable devices with a crystallized immunosuppressant drug… FULL STORY HERE
